SCGT120408-FN2 WNN10 – Indexable turning insert, FN2 chipbreaker, 90° square (Walter Tools)

SCGT120408-FN2 WNN10 is an indexable turning insert designed for versatile turning tasks where consistent chip control and predictable tool life are required

• WNN10 coated carbide grade
• FN2 chipbreaker for reliable chip control
• 90° square insert for robust turning
• 0.8 mm corner radius for stable edge life

Predictable chip control for efficient turning

The combination of the FN2 chipbreaker and the WNN10 coated carbide grade focuses on reliable swarf formation, which reduces interruptions in automated and manual turning processes. The chipbreaker geometry is designed to break chips consistently across a range of cutting parameters, so the result is improved process uptime and fewer stoppages for clearing. In practical terms, this leads to a steadier material feed and a reduction in secondary handling. The coated carbide composition offers wear resistance under typical finishing and semi-roughing feeds, supporting repeatable surface quality and longer tool cycles compared with uncoated substrates.

Robust geometry that supports heavier cuts and stability

A 90° square plate with a 0.8 mm corner radius provides strong support at the cutting edge, increasing stability during interrupted cuts and plunge turning. The insert’s 7° clearance angle helps to avoid rubbing on the workpiece while maintaining contact where it matters, and the compact plate thickness 04 with nominal size 12 fits common toolholders used in general turning operations. These geometric choices balance edge strength with versatility: the square format allows multiple index positions per insert, reducing tooling costs, while the modest corner radius delivers both improved edge life and consistent dimensional control on turned components.

Designed for reliable process selection and material coverage

The insert belongs to the Walter grade series and is specified as a coated carbide class (WNN10). This grade is intended for a broad range of turning tasks; however, material suitability should be verified against the manufacturer’s product matrix for optimised cutting data. The tolerance class G and execution T signal consistent manufacturing tolerances and a standardised fit in compatible clamping systems, supporting repeatable positioning and stable cutting conditions. For engineers seeking to standardise inserts across a production cell, the predictable tolerance and grade characteristics simplify tool selection and inventory management.

Workshop benefits: handling, indexing and stable part quality

Handling is straightforward: the square form allows several indexing positions which extends the effective life per insert and reduces downtime for tool changeovers. The FN2 chip control reduces the risk of snarled swarf in automatic lathes and improves operator safety in manual operations. From a quality perspective, the interplay of grade and geometry contributes to steady surface finish and predictable dimensional outcomes, which is particularly beneficial when running small-series production or mixed-batch machining. The robust design supports both productivity and process reliability, helping to keep machining cycles consistent under varying load conditions.

FAQ

What materials is this insert suitable for? The insert’s WNN10 coated carbide grade is intended for a broad range of turning operations; suitability for specific materials should be checked against the manufacturer’s product matrix before selection.

How does the FN2 chipbreaker influence machining? The FN2 chipbreaker promotes short, controllable chips across many feed ranges, improving process uptime and reducing swarf-related interruptions during turning.

How many index positions are available with this insert form? The 90° square format provides multiple usable cutting edges; this increases the number of index positions and extends the service life per insert compared with single-use geometries.

What does the tolerance class G mean for clamping? Tolerance class G indicates standardised manufacturing tolerances that support consistent fit and repeatable positioning in compatible insert pockets, aiding stable cutting performance.
